A coating compositions for providing substrates with oxygen barrier properties is disclosed. The substrate may be, for instance, a film, such as a polyester film. The coating composition includes a copolymer of maleic acid and acrylic acid and a copolymer of vinyl alcohol and a vinylamine. The barrier coating formed from the coating composition is typically less than about 1 micron in thickness and provides reduced oxygen transmission even at relatively high relative humidities.

Coated polymeric film with oxygen barrier properties

A metallized film and a process for making the film are disclosed. In general, the metallized film includes a polymeric film layer that is coated with a polyester coating composition. A metal layer is then formed on top of the polyester coating. The polyester coating acts as a tie layer between the metal layer and the underlying film. The polyester film composition may be formed from, in one embodiment, isophthalic acid, a sulfomonomer, and 2-methyl 1,3-propane diol. The above diol has been found to improve adhesion between the metal layer and the polymeric film layer.

Coating composition for adhering metallized layers to polymeric films

A shrinkable polymer film including a modified polyester resin polymerized from monomers including a dicarboxylic acid and a glycol, wherein the glycol includes 2-methyl-1,3-propanediol, and wherein the polymer film shrinks at least about 50% in a main shrinkage direction after ten seconds in an 80 degree Celsius hot water bath.

Propane diol-based polyester resin and shrink film

An oxygen barrier coating including polyvinyl alcohol and starch. The coating is applied to polymer film, and shows excellent oxygen barrier properties.

Clear barrier coating and coated film

A film with excellent oxygen barrier properties is disclosed. A barrier coating used thereon is also disclosed, including polyvinyl alcohol and a copolymer of maleic acid and acrylic acid, and wherein the copolymer of maleic acid and acrylic acid has a weight average molecular weight of about 3500 to about 5000. The barrier coating is typically less than about 1 micrometer in thickness and provides an oxygen barrier of less than about 0.3 cc.mil/100 in /day/atm when tested at 23 degrees Celsius and 0 percent relative humidity according to ASTM D3985. A method of stripping low molecular eight fractions from the copolymer is also disclosed. Metallized coated film according to the present invention shows surprising barrier properties.

The present invention provides a coated polymer film having heat seal properties. The heat seal coating includes a propylene diol copolyester. Preferably, the copolyester is formed from 1,3-propane diol, isophthalic acid and a sulfomonomer. A method of heat sealing using this coated film is also disclosed.

A reclaimable release coating composition is provided which includes a blend of an adhesion promoter and a silicone release agent which may be applied from an aqueous solution, dispersion or emulsion. The components form regions of adhesion promoting sites disrupted by regions of release sites on the surface of a release backing substrate coated with the composition. The different regions are substantially homogeneously distributed across the entirety of the release surface. When used as a release coating for a backing to protect an adhesive, a controlled release force of a predictable value may be obtained by providing a known weight ratio of adhesion promoter to silicone release agent in the coating composition. A substantially linear relationship is also provided between the release force required to peel a non-silicone adhesive from the release coating surface, and the weight ratio of vinyl-functional polyorganosiloxane oil to hydrogen-functional siloxane crosslinker in the release agent, such that a consistent, uniform and repeatable release force from the surface may be obtained.

Controlled release coating comprising blend of silicone polymer and

A frame is disclosed herein having an elongated base with opposite side rails defining an exposed message area therebetween occupied by a resilient pad. A message sheet is placed between the pad and a transparent window or layer which is slidably carried on the side rails to cover and protect the message sheet. Stop abutments are provided to limit sliding of the window and a snap-lock mechanism is employed for releasably retaining the window in place over the message sheet.
